R1173x SERIES
Super low on resistance/Low
voltage LDO
NO.EA-123-070828
OUTLINE
The R1173x Series are
CMOS-based positive
voltage regulator ICs. The R1173x Series have features of super low dropout, 1A output current capability, and -3mV typical load regulation at 1A. Even the output
voltage is set at 1.5V, on resistance of internal FET is typically 0.32Ω. Therefore, applications that require a large current at small dropout are suitable for the R1173x series. Low input
voltage is acceptable and low output
voltage can be set. The minimum input
voltage is 1.4V, and the lowest set output
voltage is 0.8V. Each of these ICs consists of a
voltage reference unit, an error amplifier, resistor net for setting output
voltage, a current limit circuit at over-current, a chip enable circuit, a thermal-shutdown circuit, and so on. A stand-by mode with ultra low consumption current can be realized with the chip enable pin. The output
voltage types of R1173 are fixed one in the IC and adjustable one (R1173x001x). Since the packages for these ICs are the SOT-89-5 package, HSON-6, or HSOP-6J, high density mounting of the ICs on boards is possible.
